SPECIFICATION forming part of Letters Patent No. 332,983, dated December22, 1885.

Application filed December 26, 1883. Serial No. 115,617. (No model.)

To all whom it may concernf Be it known that I, MoCLrNrooK YOUNG, ofFrederick, in the county of Frederick and State of Maryland, haveinvented certain new and useful Improvements in the Art of ManufacturingBoxes of Paper, Sto., of which the following is a specification.

My invention relates to improvements in the manufacture of boxes ofpaper, combined paper and cloth, or other suitable material, of theclass provided with end flaps, by the folding and interlocking of whichthe ends of the boxes are closed and secured, the flaps being formed atone or both ends of a box.

My objects, mainly, are to provide boxes which may readily and withoutinjury be folded iiat for packing and transportation, and toautomatically produce tubes to form such boxes from alongitudinally-creased strip .of paper, 8vo.. by first forming thecreased strip into a attened tube by folding it upon two of itslongitudinal creases and pasting its lapped edges, and afterward, whilethe tube is in its flattened condition, severing it into short tubeswith end aps and of the length required to constitute boxes of thedesired size.

The improvements deemed novel will be particularly pointed out by theclaims after being fully described by reference to the accompanyingdrawings,which represent mechanism suitably organized in accordance withmy invention.

Figure 1 is a plan or top view, and Fig. 2 a side elevation, of theentire mechanism. Fig. 3 is a view, partly in side elevation and partlyin section, on the line 3 3 of Fig. 1, showing the main shaft, its cams,&c., and in part the pasting devices,with the parts in the positionsthey occupy after a short length or box-tube has been severed from theflattened tube and the tube-feeding devices are about to be caused toengage and feed forward the attened tube preparatory to the completionand severing of another box-tube. Fig. 4 is a View, on an enlargedscale, partlyin side elevation and partly in section, on the line 4 4 ofFig. 1, the parts being represented as in the positions occupied by themafter theflattened tube has been fed the distance required for aboxtube, and just previous to an actuation of the cutters for formingthe end flaps and severing a box-tube.

Fig. 5 is a view, partly in elevation and partly in section, on the line5 5 of Fig. 1, showing details of the pasting mechanism. Fig. 6 is aview, partly in elevation and partly in section, on the line 6 6 of Fig.1, showing details of devices for drying and pressing the pasted y atingthem. Fig. 9 is a View, partly in elevation and partly in section, onthe line 9 9 of Fig. 1, showing details of mechanism for piling thecompleted box-tubes. Fig. 10 is a bottom view of thevertically-reciprocating member of the cutters on a considerablyenlarged scale; Fig. l1, a plan view of the slotted cutter-plate orfixedmember of the cutters; Fig. 12, aview, partly in elevation and partly insection, on the lines 12 12 of Figs. 1() and 11; and Fig. 13, a View,partly in elevation and partly in section, on the lines 13 13 of Figs.10 and 11. Figs. 14 to 18, inclusive, are diagrams designed to show themanner of forming the flattened tube. Fig. 14 shows the strip as beingdrawn through three guideways. or slotted folders,by whichitis-gradually formed into a tube and attened. Fig. 15 shows the firstfolder with the partially-folded strip; Fig. 16, the second, and Fig. 17the third or final, folder with the tube completed. Fig. 18 shows thefinal folder with the side slots of the first and second foldersrepresented by dotted lines. Figs. 19 and .20 are diagrams designed torepresent the various steps performed in the formation of the box-tubes.Fig.

21 shows in perspective one end of an opened boxtube with its flapsunfolded. Fig. 22 isa similar view with the end of the box partiallyclosed by the folding of the flaps; Fig. 23, a like view with the end ofthe box closed and secured. Fig. 24 is a bottom view of modified form ofcutters, and Fig. 25 is a plan View of a modified form of slottedcutter-plate for use in connection therewith. Fig. 26 shows foldedbox-tubes of modified form. Fig. 27 is a per- IOO spective view of themodified box/tube open with its fiaps unfolded.

A suitable base or frame, A, is provided, as in' turn to be described,with sundry crosspieces, uprights, brackets, e., to support variousparts ofthe mechanism, and has bearings c a at its ends for a main ordriving shaft, A', which is near one side of the frame, and actuates allthe working parts when operated in suitable way, as by a driven bandpassing around the fast pulley A2.

Webs or strips of paper or its equivalentfronl which the boxtubes are tobe made are wound upon rolls or spools,which are in turn placed inposition to supply the strips to the tubing mechanism, as required. Asshown, a roll of paper, B, is supported by its spool on a shaft, I),secured to a post, B, of the framebase. A spring, b', adjustably securedin position at its lower end, bears at its uppcrcnd against a collar orannular shoulder, B, of the spool to keep the paper under tension 0rprevent its too free unwinding. The tension of the spring may be varied,so as to increase.

or lessen the force with which it bears on the spool,by adjust-ing thenut ofthe upperone of the pair of bolts b2 b2, by which the spring isfastened in place.

The strips of paper are prepared for use previously to winding them intorolls by creasing them longitudinally throughout their extent uponparallel lines-in this instance six in number. These creases 1 2 3 4 5 6are shown clearly in Fig. 19. Upon lines delined by two of thesecreases, (those numbered 2 and 5,) the strip is afterward folded datwhen tubed. The remaining four creases, 1 3 4 6, locate the longitudinalcorners of the boxes, as in turn will be made fully apparent. Therectangular boxes made in accordance with my invention, as shown inFigs. 21, 22, and 23, are nearly but not quite square in crosssection,the dialnetrically-opposite sides in which the creases 2 and 5 areprovided being equal and of somewhat greater Width than the tworemaining sides, which equal each other. It follows, therefore, (seealso FiO. 19,) that the spaces between the creases 1 and 3 and 4 and 6,respectively, correspond in width, and exceed in width the spaces between the creases 3 and 4 and 6 and 1, respectively, which correspond.rPhe creases 1, 3, 4, and 6 predetermine the boX-c0rners, while thecreases 2 and 5, which are respectively` midway between the creases 1and 3 and 4 and 6, predetermine the lines of folding the flattened tube.

In tubing a strip its edges lap (see Fig. 19) so that, as in thisinstance shown, the outer or overlapping edge, 7, terminates at thecorner `crease 6. Therefore the distance from the crease 1 to the edge 7equals the distance between the corner creases 3 and 4. The stripterminates at its underlapping edge 8, to which the paste is applied,`quite close to the crease 6, the distance between this edge and thecrease 6 being, as shown, less than half as great as that between theedge 7 and crease 1. However, if preferred, the distance between thecrease 6 and the adjacent edge 0f the strip may equal that between theedge 7 and the crease adjacent to it, so that one side of the box may beof double thickness throughout. The strip is interinittingly acted uponby feeding devices in turn to be described, so that it is fed at cachactuation a distance equal to the length of a box tube or section of theflattened tube required to form a box. The strip passes from the sourceof supply to the action of folding devices, which, as in this instanceshown, consist of three slotted plates, C C C2. As the strip is drawnthrough the slot c in the first folder, C, its edges are turned up, thepartial folding of the strip being on the lines of the creases2 andNext. in passing through the slot c ofthe second folder, C', one edge ofthe strip is folded down and the other edge is partiall y turned down.After this the passage of the partially-tubed strip through the slot c"of the final folder completes the tubing operation, paste having beenapplied by suitable means to the first-turned edge of the strip justafter the action thereon of the second folder. (See Fig. 19.) rlhefolders are supported by uprights D D D2, secu red to the frame-base.YAfter the formation ofthe iiattened tube it is pressed and the pastedried preparatory to forming the end flaps of the boxes and cutting itinto short lengths, which I term boxtubest It should be noticed that aninternal support or "former" for the tube is dispensed with.

As shown, the pasting mechanism and its actuating devices arc asfollows: The line of paste d is applied to the paper by a roller, d',secured to a rotary shaft, di, turning in bearings in arisingAand-illing frame, shownas formed by oscillating orverticallyvihrating arms E E, carried by a rock-shaft, E', mounted inbearings in fralneposts E E. A rotating shaft, E3, is supported inbearings in these posts above the rock-shaft, and is driven from thedriving-shaft A by a belt, c. This belt passes around pulleys e c',supported on astudshaft secured to a bracket, F, and thence around apulley, ci, fast on the shaft E3. A belt, c, passes around anotherpulley, f, on this shaft and around one ofa pair of connected pulleys,ff, loosely mounted on the rock-shaft E. AnotherI belt,f2, passingaround the other one of the pair of united pulleys, also passes around apulley, d, on the shaft d2 of the paste-apply ing roller and so rotatesit. A paste-reservoir,

IIO

F', is supported on a frame cr0ss-bar, F2, and

a roller, F, fast on the shaft E3, projects into the paste, so that whenthe shaft of the pasteapplying roller d is rocked upward this roller isbrought against the paste-coated periphery of the roller E, and issupplied with paste to be applied to the paper strip when the shaft d isswung down.

` The devices next to be described for lifting and depressing the shaftcl2 by imparting niotion to the rock-shaft E'are so timed relatively tothe aetnations of the mechanism by which the strip and tube are fedthrough the machine that the paste-applying roller dis lifted to becoated with paste on its periphery and then lowered into its operativeposition during the intermissions in the operation upon the strip andtube of the feeding mechanism, so that as the strip is fed along at eachactuation of the feeding mechanism the freshlycoated pasting-roller willapply paste to it. A rock-shaft,G, is supported above and parallel withthe driving shaft in bearings in framebrackets G G. A crank-arm, g, fastto this rockshaft near one of its ends,has a universally-jointedlink-connection, g', with one of the arms E of the rock-shaft Eof theframe supporting the shaft of the pasting-roller d. A crank-arm, g2,fast to the rockfshaft G, near its end opposite that to which the crankg is secured, has link-connection g3 with the outer end ofa lever, G2,pivotally supported at its heel end, and clrrying a stud, upon whichrevolves a roller, g4, actuated by a cam, G3, fast on the driving-shaft.The cranks g and g2 project in opposite directions from their rockshaft.The roller g", at the outer end of the lever,projects into thedouble-walled track G4 ofthe cam. The lever is vibrated by the roller asthe roller is operated upon by the cam to cause the feeding mechanism toclamp and release the tube, as soon to be described.

Froni the above description (see Figs. l, 2, 3, 5, and` 7) it will beunderstood that while that portion of the cam track G4 extending from 9to 9, Fig. 7, is acting on the roller g4 the paste-applying roller diselevated to bring it in contact with the reservoir-roller F3; that therollers are kept in contact while the camactuated roller is borne uponby that part of the cam-track extending from 9 to 10; that thepaste-applying roller is lowered by the action on t-he roller gft ofthat part of the cam-track .extending from l0 to 1l, and brought incontact with the paper, as indicated in Fig. 19, and that thepasting-roller is kept in contact with the paper while the camtrackroller is being acted upon by that portion of the track extending from11 to 9. At each revolution of the driving-shaft the above-describedactu- -ations of the pasting devices are repeated. -The strip and tuberemain stationary While the pasting-rolleris out of contact with thepaper, and while the roller is in contact with the paper it is fed alonga distance corresponding with the length ofa box-tube.

The pasted seam of the attened tube is pressed and the paste dried bymeans, as follows: The tube passes above and in contact with a hollowplate or steam chamber, h, to .which steam is admitted vand allowed topass off by pipes H H and suitable connections. (See Figs. 1,2, 4, and6.) While the tube is being dried by the heating-plate and supportedthereby, it is also pressed and smoothed by blocks or irons H bearing onthe tube and supported against other than vertical movement by a slottedor centrally-open frame, h. This frame surrounds-the blocks, which are,ing the tube.

left free to be self-adj usting vertically to accommodate themselves tovariations in thethickness of the tube andthe inequalities of itssurface. The heater and the frame of the pressers are supported by armshA2 h2, one of which is secured tothe before-mentioned frame-upright D'zand the other to another upright, D3.

The feeding mechanism and means for transversely creasing the flattenedtube to facilitate the folding of the end [laps of the boxes are, as inthis instance shown, as follows: The before-mentioned lever G2, carryingthe roller g4, actuated bythe cam G3, is supported at its inner or heelend, so as to vibrate lbetween the arms of a forked bracket, I, Figs. land 4. firmly fastened to a frame cross-piece, I. A sliding rock-shaft,I2, is supported so that it may be readily moved endwise, in bearings inthe arms ot' the bracket l, and is provided with a longitudinal groove,z'. The lever G2 is fitted about this rock-shaft and has a featherengaging with its groove, so that reciprocating movement of the shaftindependently of the lever is-allowed, as will readily be understood,while the rocking movement is imparted to the shaft by the lever as itis vibrated by its actuating-cam. This rockshaft is connected at one endwith a sectional reciprocating clamp for feeding and transversely creas-The rock-shaft end passes loosely through a down wardly-projecting plateor wide arm, j, having rigid connection at j' clamp, the rock-shaftbeing connected with the arm, so as not to interfere with its rockingmotion, by means of collars fastened to it Vat the opposite sides of thearm, as will readily be understood. The upper section, .J, of the clampreciprocates vertically toward and away from the lower section, J.rocation of the upper clampsection is imparted to it by the rock of theshaft I. This shaft has a slotted crank-plate, I3, fastened to its end.(See Figs. 4 and 7.) Apin, i,is carried by a downwardlyprojecting arm,J2, having rigid connection with the upper clampsection, and this pinengages with the slot i ofthe crank la.' A yoke shown as formed bydownwardly-projecting side arms, J3 J3, and a cross'piece, jt, serves tomake the connection between thearm J2 and the clamp-section J. Thisclamp-section is guided in its up and down movements by the slidingconnection of its arm J2 with the armj of the lower clampsection. Adovetail guideway connection is iliade between these arms by providing arecess undercut at its edges in the arm j, and forming the arm J2 withbeveled edges fj, to t in the recess. The arms J3 J3 of the yoke,secured to the top section of the clamp, embrace the bottom section ofthe clamp andaid in maintaining the top section in proper positionthroughout its movements. It will be seen that the connection of theupper and lower sections of the clamp is such as cause them to movetogether when reciprocated lengthwise ofthe machine Ato engage and feedThe vertical reci p- IOO IIO

the tube. Four ribs, KKKK, secured transversely in pairs upon theadjacent faces of the upper and lower sections of the clamp, serve toengage and release the tube. These ribs are faced with rubber or itsequivalent to insure a proper grip upon the tube without possibiiity ofinjuring it. The transverse creases 12 12, Fig. 20, in the tube, fordetermining the lines upon which the end iiaps are to be folded, areformed by the two pairs of recessed and lipped ribs K K K K', secured tothe adjacent faces of the upper and lower sections of the clamp andcrosswise ofthe sect-ions. The creasingribs are adjustably secured inplace by means of slots lo 7c in the clampvsections and the bolts k andtheir nuts, as will readily be understood from the drawings. The clampis provided with a guideway for the tube, (shown as formed betweenangle-lugs K2 K2) securedto the under side of the top section of theclamp by means of screws or bolts la* k2. The distance between theseguide-lugs corre spends with the width of the flattened tube, andconsequently the proper position of the tube for creasing is insured.The bottom section of the clamp has sliding supporting-connection with alongitudinal frame-bar, L, corr nected at one end with thebefore-mentioned frame cross'piece I', and secured at its opposite endto another frame cross-piece, L. As shown, a dovetail groove in theclamp bottom section and an inc1ined-sided bar or rail, l, secured uponthe bar L, constitute the supporting and sliding connection of theela-mp with the frame, and the clamp is reciprocated, so as toalternately approach and move away from the roll of paper,by means of acam, M, a lever, N, and a bar or dat rod, L2, connecting the lever andlower section of the clamp. The connecting-bar` L2 is pivoted at one endto the feeding-clamp, and is adjustably secured at its opposite end tothe lever N by means of the clamp-plates l Z and their bolts, and abolt, Z2, passing through a longitudinal slot, N', in the lever, andheld in the desired position therein by a washer and nut, n, beneath thelever. The securing-bolt Z2 turns freely in the lower one of theclamp-plates Z. A head on the upper end of this bolt, countersunk in theupper surface of the lower clampplate, prevents accidental displacementof the bolt, as will readily be understood from inspection of Figs. 4and 6. TheleverNis provided with a hub or bearing-sleeve, n', by whichit is pivoted on a studshaft, at, supported by a brack et or arm, h2, ofa crosspiece. N3, ofthe frame. A roller, on, carried by the lever,enters the peripheral slot or track M of the cam M, which is fast on thedriving-shaft.'

From the above description the operation of the intermittinglyactuatedfeeding and creasing mechanism will he understood to be as follows:While that portion ofthe track G4 ofthe cam G3 extending from 9 to 9 isacting on the roller g4 of the lever G2 the outer end ofthe lever isdepressed and the upper section of` the clamp is elevated by the rock ofthe shaft I2 and its slotted crank to release the tube from the creasingand clamping ribs. During this timethe portion 13, Figs. 1, 2, and 6,.of the track M of the cam M is acting on the roller m of the lever N,and this lever is held stationary. At this stage of the operation thefeeding and creasing clamp is at the end of its movement in thedirection of travel of the tube and strip. The top section of the clampis held up while the portion of the cam-track G4 extending from 9 to 10is acting on the roller of the lever G4, as during this stage of theoperation the lever remains at rest. During this time the portion 14,Figs. 2 and 3, of the cam-track M acts on the roller m and moves thelever N about its pivot, so that by Way of the connecting-bar L2 thefeeding-clamp is moved toward the paper-roll a distance equaling thelength of a box-tube. (During this stagein the operation of the feedingmechanism the tube is being acted upon by the cutting and end-formingmechanism, to be described, and thus held against accidental retrogrademovement.) Next, the action upon the roller g4 of that part of thecamtrack G4 extending from 10 to l1 elevates the outer end of the leverG and imparts a downward movement to the top section of thefeedinglclamp by way of the rockshaft I2, thus clamping the tube. Duringthis stage in the operation the pasting-roller is.

brought into position to apply paste to the partially-tuberi strip, asbefore explai ned, and movement of the feeding-clamp in the direction ofthe length of the tube is prevented by the action of the part 15, Fig.3, of the camtraek M ou the roller m to hold the lever N at rest. Thefeeding movement of the tubeclamp is next imparted to it by the actionof the part 16 of the cam track M on the roller m, thus imparting theneeded movement to the lever N and the connecting-bar L. Thefeeding-clamp comes to rest when the part 13 of the camtrack M ispresented `to the roller m. During the feeding movement of thetubeclamping devices that part of the cam-track G4L extending from 11 to9 acts on the roller g, resulting in holding the clamping-ribs firmlyagainst the opposite sides of the tube until'it is fed the distanceneeded. The above-described operations are repeated at each revolutionof the driving-shaft- The cutters for severing the box-tubes and formingthe end flaps consist ofan upper movable member formedby a series ofknives carried by an intermittiriglyactuated vertically-reciprocatinghead, O, and a lower fixed member or slotted plate,iO. As in thisinstance shown, there are fourteen knives and the two ends of eachbox-tube are formed alike. The 4knives P P, in connection with thecorresponding portions Q Q ofthe slots in the plate O', form thelongitudinal slits 17, Fig. 20, in the flattened tube in the lines ofthe creases 1, 3, 4., and 6. The knives p p, in connection with theportions q q of the slots in the plate O', cut through the tube at 18 18from its edges (the IOO lines of the creases 2 and 5) to the slits 1717. Knives P P and p p', in connection with the portions Q Q and q q ofthe slotsin the fixed member of the cutters, form the longitudinal slits19 19 and the edge cross cuts 20 20. Knives P2 and p, in connection withthe porl tions QZ and q2 of the slots in the fixed member of thecutters, cut across and through the tube from one of the slits, 17, tothe other. Knives P3 and p3, in connection with the portions Q3 and g3of the slots in the fixed member of the cutters, cut across the tubefrom one of the slits, 19, to the other. Cutters P4 and p, in connectionwith slots Q* and g4 in the fixed member of the cutters, form slits 21and 22 in the tube, which extend, respectively, part way between theslits 17 17 and 19 19. It will be seen that when operated, as presentlyto be explained, the cutters in severing the box-tubes form both ends ofthe respective tubes precisely alike, each end having fourfolding-liaps, two of which, at diametrically opposite sides of the box,have the slits 21 or 22 and hooks 23 or 24,which interlock with theslits, making a double fastening, as clearly shown in Fig. 28. Theslitted hook-'ended flaps 25 25 are somewhat longer than the fiaps 2626, as pieces are cut out of the tube at the adjacent ends of twobox-tubes between vthe pairs of cutters4 p p 3o p p. Thedifferencein thelengths of the flaps 25 and 26 equals half the distance which separateseach of the cutters p from the cutter p', adjacent to it. With lthepieces cut from the tube between the cutters p p' p p there are also cutout pieces of shapes corresponding with the outlines of thehereinafter-mentioned blocks O4I and o4, as will readily be understoodfrom inspection of Figs. 10, 11, and 20. The various knives are suitablyfastened to the cutter-head O, as by means of blocks O2 o2 O3 o3 O4 o4O5 and oi"` to which the cutters are respectively detachably secured byscrews, while the blocks are fastened to the head by tap-bolts, asplainly shown. The slotted plate or fixed member O of the cutters issecured in place upon its bed or supporting block R by means of bars o oand fastening-screws. A space is thus left beneath the cutter-plate topermit of the knives projecting through its slots and allowing them tobe given sufficient movement to insure proper action. The cutterbed-block R is adjustably secured in place upon the frame of the machinein suitable way. It is shown as fastened to a frame bar or plate,R,which is secured to the frame crosspiece L. The cutter-head O isreciprocated vertically, and, as shown, is supported and actuated, aswill now be described, referring particularly to Figs. 4 and 8. Theupright arms r 1' of a carrier frame or yoke are bolted or otherwisefirmly fastened at their upper ends to the cutter-head. The lower end orcross-bar, 1, of the yoke has a downwardlyprojecting arm, R2, firmlyfastened to it, and, as the yoke is reciprocated, this arm slides up anddown in a suitable guideway, r2, in aplate or block, R3, which issecured to the frame cross-piece L. A lever, S, is provided with a hubor sleeve-bearing, S', by which it is pivoted so as to vibratevertically about a stud, s, secured to the block R3. The lever isprovided with a slotted heel projection or short arm, S2, and a pin, s',on the yoke-arm R2 is engaged by the slot s2 of the lever-heel. At itsouter end thelever carries aroller, t,which projects into the cam grooveor vtrack T of a cam, T, fast on the driving-shaft.

From the above description it will be understood that in the operationof the machine the cutters are actuated as follows: While the portion ofthe cam-track T extending from 27 to 28 is acting on the roller t thereciprocating member of the cutters is brought down and acts on thetube. Immediately after the cutters engage the tube the elevation, ashereinbeforeA explained, of the top section, J, of the feeding-clampleaves the tube free, and while the feeding-clamp is moving toward thestriproll and until it has again engaged the tube the roller tis actedupon by that portion of its cam-track extending from or near 28 to 29.Preparatory to the feeding of the tube by the clamp the roller t isacted upon by that portion of its cam-track which is between 29 and 30,and the reciprocating member of the cutters is lifted clear of theflattened tube, from which it has severed a box-tube. The feeding clampnext pushes the tube along over the slotted cutter O' the distancerequired for a box-tube, and during this feeding action, and while theroller tis engaged by that portion of its cam-track extending from 30 to27, the cutter-head is held up. A repetition of the above-describedoperations of the cutters take place at each revolution of thedrivingshaft. The respective box-tubes, as they are in turn producedfrom the iiattened tube by the cutters, rest for a greater portion oftheir length over and upon a plate, u, secured to a shelf or bracket, U,which is suitably attached to and supported by the frame-plate R. Figs.1, 2, and 4.) rlhe shelf-plate projects at one end beneath the slottedcutter-plate O, and at its opposite end is formed with notches andprojections to correspond in shape or register with the end of the tubewhich rests upon it. guides for the tube. A striker-plate, U', is formedat one end with projections the counterpart of the notches in the plateu, and with notches corresponding with the projections of this plate, sothat, as will presently be explained, the box-tubes, as in turnprojected along and beyond the shelf-plate, are struck down andcompactly piled upon a table, V. The table V is self-adjustingvertically, so as to descend gradually as the box-tubes are piled uponit.

The striker is actuated by means as follows: The striker proper or plateU', as shown by Figs. 1, 2, 4, and 9, is secured to averticallyvibrating a! m, V, which is pivoted at its heel end to frameuprights w w. A weight, fw', on the striker-arm acts with a tendency tomove it downward, or else to hold it down as far as its elevatingdevices will permit. The striker arm is provided with a roller, fr,which is journaled between the lower ends of downwardly-projecting shortarms X' X, fastened to the strikerarm. rIhe roller bears against a cam,Y, fastened to the driving-shaft. It will be seen that during the t-imethe portion y of the cam which is of least radius is acting on theroller the striker is in its depressed position; that during the timethe portion y of the cam is acting on the roller the striker is beingelevated; that while the portion Y of the cam which is of greatestradius is acting on the roller it is in its elevated position, and thatduring the action of the portion y2 on the roller the striker is causedto descend by its weight into the depressed position. The descent of thestriker takes place while the cutters are acting on the tube, and abox-tube previously formed and thrust along by the feed of the tube ispressed down upon the table or pile of box tubes thereon. As thebox-tubes are accumulated the table yields to the pressure of thestriker, and thus gradually descends until a pile is completed. It willbe seen that a complete vibration or up and-down movement is imparted tothe striker at each .revolution of the d riving-shaft,

' and that the box-tubes, if not completely severed by the cutters, areseparated from each other by the action of the strker in connection withthe shelf-plate u, above the level of which the striker ascends whenmoved upward, and beneath the level of which it descends when moveddownward to strike off and pile up the box-tubes as they are in turnprojected over the vertically-moving table.

It :is not deemed necessary to enumerate advantages of my improvements,as they are obvious.

I do not wish to be understood as limiting my invention to the detailsof construction and arrangements of parts 4as hereinbefore particularlydescribed, as my improvements may be modified in many respects, and someof the novel features or essential cooperating parts may be used withoutthe other.

As one of the modifications of my invention, which it maybe deemedadvisable to make under some circumstances, may be mentioned thealteration ofthe cutters, so as to make box tubes each of which shall beprovided with the hook-ended iiaps and slits 21 at one of its ends only,the other end being formed with four plain or simple rectangular tlaps,all of onelength: To make such boxtubes, it would only be necessary toomit one halt' of the knives-say all to the right of the section-line 1212 of Fig. 10-and provide along crossknife in the plane of said line tocut entirely across the tube, and two slitting-knives, such as P P,except that they would have to extend to the cross-knife, and, further,to omit all portions ofthe slots in the cutter-plate O', which arelocated to the left of a line crossing from Z Z, Fig. 11, and provide along crossslot for the long crossknife, and two slots, such as Q Q,except that they would intersect the long cross-slot to correspond withthe altered slitting-knives. A boxtube so formed with the fourcorresponding rectangular iiaps at one end might have such endclosed,when the tube is opened out to form a box, by folding and pastingthe tia-ps or securing them by eyelets, fastening-staples, die., inwell-known way.

As a further moditi cation in the form of the cutters and the box-tubesto be made maybe mentioned the following: (See Figs. 24l to 27inclusive.) The cutters as thus modified are designed for severing theiiattened tube into boXtubes of square cross-section, instead of formingthese tubes of other rectangular form in cross-section. The modifiedbox-tube is shown as having flaps at one end only. The cutters forforming such a tube consists of a long knife, 27, which cuts entirelyacross the flattened tube, thus forming the tube at one end withouttlaps, and of other knives, 28, 29, 30, 31, and 32. The slots in thecutterplate (shown by Fig. 25) correspond with the knives of themodified form of cutter. The knife 28 cuts the tube at the edge 33. Theknife 29 forms a slit, 34, in two adjacent flaps at one side of thecenter of the box-tube. The knives 30 and 31 form the triangular openingbetween the slitted iiaps and inclined edged iiaps of the box-tube, andthe knife 32 cuts a piece from the box-tube at the edge 36.

When box-tubes square in cross-section are made, the strip from whichthe flattened pasted tube is formed is provided with four longitudinaland parallel creases instead of IOC IIO

be selected for severing a folded box-tube cut square across or withoutiiaps at one end, and with flaps at its opposite end of any suitableform, may be mentioned the following: a long knife arranged in the planeof the line l2, Fig. l0, of the cutter-head, working in connection witha corresponding slot in the plane of the line Z` of the cutter-plate,Fig. ll, together with the omission of all the slots in the cutter-plateat the right of the line Z, Fig. l1, and the knives of the cutter-headat the left of the line 12, Fig. 10.

By making the tubes of different lengths and of proper relative sizes-incross-section it is obvious that they may be adapted to Vform slidingboxes, or boxes in which one section slides within the other, as well asto form boxes and tops therefor, and also what may be termeddrawer-boxes,77 such as used for matches, Src., and in which there is acase provided to inclose a draw which slides in and out.

I claim as of my own invention- 1. As an improvement in the art ofmanufacturing boxes of paper, 8vo., the hereinbe-y fore-described methodof forming folded boxtubes, consisting in advancing a flattened tube,severing the boxtubes, and at the same time forming their end flaps,substantially as hereinbefore set forth.

2. As an improvement in the art of manufacturing boxes of paper, &c.,the hcreinbefore-described method of forming folded boxtubes, consistingin advancing a flattened tube, transversely creasing the tube on linesupon which fold the end flaps of the boxes to be made, severing thebox-tubes, and at the same time forming their end aps, substantially ashereinbefore set forth.

3. As an improvement in the art of manufacturing boxes ofv paper, Src.,the hereinbefore-described method of forming folded boxtubes, consistingin supplying a strip creased longitudinally upon parallel lines topredetermine the location of the corners of the boxes to be made,forming the tube by folding upon lines predetermined by two of saidcreases, advancing the flattened tubes, severing the boxtubes, andforming their end flaps, substantially as hcreinbefore set forth.

4. As an improvement in the art of manufacturing boxes of paper, &c.,the hereinbefore-described method'of forming folded boxtubes, consistingin supplying a strip creased longitudinally upon six parallel lines,four of which creases predetermine thelocation of the box corners,forming a pasted flattened tube folded upon lines predetermined by twoof suchcreases, transversely creasing the tube, and severing theiiattened tubel into box-tubes with end flaps folding upon the lines ofthe transverse creases, substantially as hereinbefore set forth.

In testimony whereof I have hereunto subscribed my nanie this 22d day ofDecember,
